Many players did this before me, but here's my version. I tried to change as little as possible of the original Warmaster rules.
From my
blogpost at BoardGameGeek.
If you like miniatures and boardgames, then you might like Warmaster a lot! It's a great set of rules meant to use with miniatures on a tabletop. The gameflow is smooth and it allows you to fight a battle in one evening. This is in contrast with Warhammer Fantasy Battle, a rules-set meant for 28mm miniatures. Warmaster is designed to use with 10mm miniatures.
You can find quite a lot of articles on the internet about trying to play Warmaster with 28mm armies. Many fans added their own houserules, some with clever calculations to convert ranges and distances.
Because WARMASTER IS GREAT, I'd rather stay as close to the original rules-set as possible. (Note: I followed the same design idea for "Allied HeroQuest". Trying to keep all the official rules intact and only tweaking and updating minor things.)
The official rulebook and armylists for Warmaster remain unchanged. Leave all distances as they are (in cm). We do need a new definition for 'stands'. In Warmaster a 'stand' equals one playing piece.
Infantry20mm square base: 1 stand = 5 bases in a row (10cm wide)
25mm square base: 1 stand = 4 bases in a row (10cm wide)
40mm square base: 1 stand = 1 base (4cm wide)
25mm round base: 1 stand = 4 in a row (10cm wide)
e.g. For Bretonnian Men-at-arms on 20mm square bases, to create a unit of three stands, this results in 3 rows of 5 Men-at-arms. On the table it will look like a WFB regiment 5 wide and 3 deep.
Ranged Infantry20mm square base: 1 stand = 3 in a row (6cm wide)
e.g. For High Elf Archers on 20mm square bases, to create a unit of three stands, this results in 1 row of 9 archers. On the table it will look like a WFB regiment 9 wide and 1 deep.
Cavalry (or infantry monsters)25-50mm square base: 1 stand = 2 side by side (5cm wide)
40mm square base: 1 stand = 1 base (4cm wide)
e.g. This results in 6 Chaos Knights in one row. Or three Minotaurs.
Chariots3 stands = 1 base (5cm wide)
Chariots use only one physical miniature stand, but the official stats remain intact. Use tokens or dice to indicate damage.
The army lists need a minor adjustment to fit most people's WFB armies. Following Monstrous Mounts are available to High Elves, Empire, Bretonnia and Dark Elves:
Griffon 80 points
Pegasus 15 points
Bear 10 points
Following unit sizes may be halved. The new amount of hits and points cost are below.
1 Empire Cannon: Hits 1 - Points 45
1 Undead Bone Thrower: Hits 1 - Points 35
1 Elven Bolt Thrower: Hits 1 - Points 35
1 Dwarf Cannon: Hits 1 - Points 45
1 Dark Elf Bolt Thrower: Hits 1 - Points 30
1 Kislev War Wagon: Hits 2 - Points 70
I have converted my 5th edition WFB army lists. A WFB army worth 2000 points will be +/- 1000 points in Warmaster.
Well... that's about all. It will work. Now's the chance to see your 28mm armies on the table WHILE having only one game evening each month...
